Electrogalvanizing Performance Application Knowledge (SECC)

Electrogalvanizing performance knowledge: In recent years, the use of surface treatment steel plates has been amazing development. After the electric galvanized continuous production unit is introduced, it can produce a variety of electric galvanized surface treatment steel plates with high quality and excellent performance. These electrogalvanized surface treated steel plates are widely used in household appliances, steel furniture, office equipment, automobiles, building materials and other fields, and have been highly praised by users.

Substrate: The galvanized substrate is obtained by pickling and annealing the hot rolled coil of corresponding specifications into cold rolled coil.

Cleaning: alkaline washing and pickling are carried out on the surface before electroplating to make the strip surface clean.

Electroplating: electrogalvanizing or zinc-nickel alloy on a washed strip surface, single side or differential thickness.

Surface treatment: According to different uses, after electroplating, phosphating, passivation, oiling and fingerprint resistant, self-lubricating fingerprint resistant treatment.

Electrogalvanizing product specifications and post-treatment:

Variety: Electrogalvanized steel surface treatment can be roughly divided into oiling, chemical passivation, phosphating, fingerprint resistance, self-lubricating fingerprint resistance treatment.

The electroplated zinc substrate is cold rolled and annealed with hot rolled coil of corresponding specifications. The mechanical properties are the same as those of the substrate except for the coating.

Chemical passivation: no chromium passivation treatment, the purpose is to improve corrosion resistance.

Phosphating: In order to improve the painting performance, the surface of galvanized phosphating and chromium-free sealing treatment.

Fingerprint resistant plate: For the electronics industry, the internal parts of household appliances, to be repeatedly touched by hand during processing, in order to prevent fingerprint sweat on the steel plate, fingerprint resistant coating on the surface of the steel plate.

Self-lubricating fingerprint plate: For micromotors and motor shell parts, self-lubricating coating is performed on the surface of the steel plate in order to protect the surface of the steel plate and reduce damage during processing.
